# 计划 03: 网关扩展方法
|
|
|
|
## 目标
|
|
|
|
创建 Extensions 类用于快速 IoC 注册 Gateway 服务。
|
|
|
|
**目的:** 支持单行注册所有 Gateway 服务，类似于 AddPlatformCore。
|
|
|
|
**输出:** 包含 AddGatewayCore<TContext> 方法的 GatewayExtensions.cs。
|
|
|
|
## 上下文
|
|
|
|
@Fengling.Platform.Infrastructure/Extensions.cs (模式参考)
|
|
@Fengling.Platform.Infrastructure/GatewayDbContext.cs (来自计划 02)

## 任务
|

|
|
<task type="auto">
|
|
<name>任务 1: 创建 GatewayExtensions</name>
|
|
<files>Fengling.Platform.Infrastructure/GatewayExtensions.cs</files>
|
|
<action>
|
|
创建 GatewayExtensions 静态类：
|
|
|
|
```csharp
|
|
public static class GatewayExtensions
|
|
{
|
|
public static IServiceCollection AddGatewayCore<TContext>(this IServiceCollection services)
|
|
where TContext : GatewayDbContext
|
|
{
|
|
// 注册 Gateway stores
|
|
services.AddScoped<IRouteStore, RouteStore<TContext>>();
|
|
services.AddScoped<IInstanceStore, InstanceStore<TContext>>();
|
|
|
|
// 注册 Gateway managers
|
|
services.AddScoped<IRouteManager, RouteManager>();
|
|
|
|
return services;
|
|
}
|
|
}
|
|
```
|
|
|
|

<files>Fengling.Platform.Infrastructure/Migrations/</files>
|

<action>
|
|
为 Gateway 实体生成 EF Core 迁移：
|
|
|
|
1. 创建初始迁移：
|
|
- 从 Infrastructure 目录
|
|
- 迁移名称: InitialGateway
|
|
|
|
2. 验证迁移包含：
|
|
- GwTenants 表
|
|
- GwTenantRoutes 表
|
|
- GwServiceInstances 表
|
|
- GatewayDbContext 中定义的所有索引
|
|
</action>
|
|
<verify>
|
|
<automated>dotnet ef migrations list --project Fengling.Platform.Infrastructure</automated>
|
|
</verify>
|
|
<done>迁移已生成并列出</done>
|
|
</task>
|
|
|
|
</tasks>
|
|
|
|
## 验证
|
|
|
|
- [ ] GatewayExtensions.cs 可编译
|
|
- [ ] AddGatewayCore 方法注册所有服务
|
|
- [ ] 迁移成功生成
|
|
- [ ] Build 通过
|
|
|
|
## 成功标准
|
|
|
|
Gateway 路由功能完全集成并可使用。
|
|
|
|
## 使用示例
|
|
|
|
```csharp
|
|
// 在 Program.cs 或 startup 中
|
|
services.AddPlatformCore<PlatformDbContext>(options =>
|
|
options.UseNpgsql(connectionString));
|
|
|
|
services.AddGatewayCore<GatewayDbContext>(options =>
|
|
options.UseNpgsql(gatewayConnectionString));
|
|
```
